NON-RE FlLLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 782,640, dated February14, 1905.

Application filed June 7, 1904. Serial No. 211,512.

' the neck of the bottle below its mouth and held in position by meanson the stopper engaginga groove in the bottle-neck.

The object of this invention is-to provide a simple, effective, andinexpensive stopper having fingers arranged to lock in a groove formedin a bottle-neck and a hollow body through which fluid passes from thebottle. A valve is provided within the body for closing the outlet fromthe stopper until the contents of the .bottle are to be used, at whichtime the valve is unseated by suitable means and cannot thereafter berestored to position.

In the accompanying drawings, Figure 1 represents a sectional elevationof the neck'of a bottle with my improved stopper shown in place therein.Fig. 2 is a bottom plan view of the stopper removed from the bottle.Fig. 3 is a central cross-sectional view of my stopper with valve inclosed position on line a a, Fig. 2. Fig. 4 is a similar view of thestopper in open position. Fig. 5 is a view of my stopper in sideelevation before the securingfingers are turned up. Fig. 6 is a detailplan view of the valve used with my stopper. Fig. 7 illustrates amodified form'of stopper.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 indicates the neck of a bottle, within which is formed acircular hori- Zontal groove 2 and a rib 3 below the groove.

. The stopper as a whole (represented by 4) comprises an inner body 5,an outer or cap piece 6, having fingers 7, and a valve-disk 8. The body5 is cup-shaped, flat on the bottom, with sides flaring outwardly towardthe top, the upper edge 9 of which has a slight outward roll, as shown,while through its bottom a perforation 10 is formed. The body 5 iscovered by the cap-piece 6 and connected there- 'edge 9, as indicated by11.

to by beading it around the outwardly-rolled Beneath the bead 11 is a,circular groove 12, forming a seat for an annular rubber packing-ring13. Below the groove 12 the cylindrical side wall of the cap-piece 6 isslitted to form a series of depending fingers 7, (see Fig. 5,) which arebent the groove 2 in the bottle-neck when the stopper is inserted. (SeeFig. 1.) The top of the cap-piece 6 is fiat andhas an opening 14 throughits center, surrounded byaflange 15.

Within the body 5 is placed a circular valvedisk 8, (see Fig. 6,) havinga plate-spring 17 centrally riveted to its upper side.

When the valve-disk 8 is in place, it bears against the inner side ofthe fiat top of the cap-piece 6 and closes the opening 14, through whichfluid escapes from the bottle, while the ends of the spring 17 are bentupwardly and project through said opening 14 and rest on the flange 15,thereby holding the valve-disk 8 substantially fluid-tight against thecap-piece.

By means of a suitable tool introduced into the bottle-neck thevalve-disk 8 may be unseated by pressing thereon with the tool. Thiscauses the spring to yield and permits the valve-disk to fall to thebottom of the body and close the opening 10. The ends of the spring 17after passing through the opening 14 tend to straighten out, as in Fig.4. If the bottle be now inverted, the contents will flow out through theopenings 10 and 14. Although the valve disk may gravitate toward theopening 14, the bowed ends of the spring 17 will contact with the top ofthe cap-piece 6 and prevent the opening being sealed bythe valve-disk.

' In the modified structure illustrated in Fig.

7 instead of slitting the cylindrical wall of the cap-piece 6 to formthe fingers 7 tongues any attempt at withdrawal. The bead 3 prevents thestopper from being pushed into the bottle. The packing-ring 13 forms atight joint between thebottle and the stopper, so that the liquid cannotpass out of the bottle around the stopper nor air into the bottle.

Having thus described the invention, what is claimed as new is 1. In abottle-stopper, the combination of a hollow body having an opening inits bottom, a cap-piece for said body having an opening in its top andfingers on its side projecting upwardly and outwardly, and a valve-diskhaving a spring thereon, the ends of said spring being adapted to engagethe opening in said top and cause said valve-disk to seal said openmg.

2. In a bottle-stopper, the combination of a hollow body having anopening through its bottom, a cap-piece therefor having a flangedopeningin its top and avertically-slitted side wall turned upwardly andoutwardly to form spring-fingers, a valve in said body adapted to sealthe opening in said top, and a spring fastened to said valve, the endsof which spring pass through said opening in the top and hold the valveagainst its seat.

3. In a bottle-stopper, the combination of a hollow body, a cap-piecetherefor, having a flat top with a flanged central opening and acylindrical vertical wall, and upwardly and outwardly turned fingersformed by cutting said wall and bending the cut portions.

' 4. In a bottle-stopper, the combination of a hollow body having anopening, a cap-piece therefor having a flanged opening in' its top andavertically-slitted side wall provided with a groove above the slits,fingers formed by bending upwardly the slitted side wall, and a valvewithin said hollow body for closing the opening in said cap-piece.

In testimony whereof I afiix my signature in presence of two witnesses.
